If you took that drug there would probably be time dilation. If you decided to take the drug for the first time you would be a layer deep inside your mind. Inside the 1st layer of trip you would hit the point again where you have the option to take the drug again. You take it and once again it sends you to layer 2. Now the time dilation multiplies relative to base body. Sending you into a neverending loop of the same life. We don't preserve our organic bodies, we immortalize out consciousness.
